6.5 Kilowatt Solar System Installed

Should cover about half my power needs.  Kyocera Solar 250W module array (Model KD250GX-LFB3) Panel Rating 250 W DC ea, Array Rating 7.5 kW DC.  System cost to install was $35,625 for Solar City.  I will be paying them at a rate of 9.9 cents per kW hour.  This rate can go up by 2.9% per year (so in 10 years it will cost what NV energy charges me right now!)  Should produce 13,773 kWh per year with a 0.5% degradation per year in performance.

The dollar schedule for my system.  So in 5 years I could buy the system form them for $18k.

Tankless Water Heater

My first electrical job.   I wired in a 60 amp circuit to my seimans panel board.  Used 6 Guage wire in a hard conduit that passed through my wall into my garage and to a 60 amp disconnect switch.

The water heater is an awesome instant heater that uses up to 13 kilowatts to heat water instantly.  It should save me about $15 to $20 per month.

New Patio Doors

Got the new patio doors $5,700 for 3 doors installed.  U value of previous doors (single pane aluminum framed) was about 1.3, these new doors a U value of 0.29 meaning they transfer about 22% the heat that the old doors would transfer.  That's big, about $1.50 per door per day in 110°F summer or 30°F winter of energy savings.  Based on degree days cooling (2574°) and heating (2508°F) for Las Vegas, the difference in U value should come out to a savings of $211 per big door per year and $158 for the smaller door.  That's a total of $580 per year giving these doors a 10 year payback from the energy savings (9 years with the tax credit).  In the mean time they look much better, work smoothly, keep down noise, and reduce temperature gradients.  Plus SCREEN DOORS!
